Technically sae30 mono qualifies as a HDEO.....so Texaco lawnmover sae30 oil (our company Petrol had rebranded Texaco oils in the past).

Nowadays....Rimula R6M 10W-40

I recall the first HDEO I ever bought was Rotella 15w40 conventional or whatever. Dad said his first was DELO SAE 40


Rotella T 15W40 back in the mid 80's. Worked for a Shell Oil Jobber. At that time, Rotella sold more HDEO than all others combined. Doubt that is still the case today.

Rotella 15w-40 for my Detroit 6.5 extremely badass turbo diesel (NOT). It has been 7.3s after that with a Dmax and 5.9 Cummins thrown in the mix....

But yes, Rotella15w-40

Delo 15W-40 for my '87 Ford F-350 XLT Lariat with the battleship International 6.9L diesel. It was a monster... and I loved that slow hulk with its 4.10 RE.

I plugged it in when it got cold in 90's Alaskan winters. Back then, that was most of the time.

It looked much like this one:

Miss the old girl. It came from a time when trucks were trucks.

I think it was Coastal fleet 15w40. I had an 83 F250 with a 6.9 IDI that I got off my dad when I was 15 and he use to use that oil in that truck, and I think that was what I used for a while. I probably had bought Delo 15w40 or Rotella 15w40 for the tractor or equipment before that somewhere along the line.
